NTE7058 Integrated Circuit Single Chip TV NTSC System Description: The NTE7058 combines all the functions required for an NTSC color TV system in a 64–Lead DIP type plastic package. This device is designed to offer a wide capability of applications from fundamental CTV to high–end MPX CTV with a quasi–parallel SIF system, requiring minimal external parts and adjustments. A quasi–parallel SIF system assures buzz–free sound reproduction.
